Bruni also dispelled rumors that she's unhappy with her role as first lady. "For me, being first lady of France is not a burden," she said. "Three years of this is much less tiring than 10 years of modeling."

Though this will be the first child for Bruni, Sarkozy has three children from his previous marriages to Marie-Dominique Culioli and Cecilia Ciganer-Albeniz. The couple have yet to announce a due date.
